Elastomeric Impact Pad with Deflection Layer for Helmet

The patent employs a multi-layer composite structure consisting of an elastomeric pad layer, a deflection layer with deflection plates, and a helmet shell. The elastomeric material absorbs impact energy through deformation, while the deflection layer redirects impact forces away from the head. This composite approach creates synergistic protection that exceeds the sum of individual components, effectively cushioning impact forces without compromising head safety.

The protective system is divided into distinct functional segments: the elastomeric pad for energy absorption, the deflection layer with separate plates for force redistribution, and the helmet structure for overall protection. This segmentation allows each component to specialize in a specific protection mechanism, optimizing the overall impact mitigation while maintaining flexibility and comfort.

The patent achieves superior impact protection in a thin profile by using composite materials with high energy-absorption-to-thickness ratios. The elastomeric pad provides efficient energy dissipation through its viscoelastic properties, while the deflection layer adds protective functionality without significant thickness increase. This composite strategy delivers adequate cushioning while maintaining a sleek, comfortable design.

The patent utilizes materials with optimized mechanical parameters, specifically elastomeric materials with tailored durometer values and thicknesses. By carefully selecting material parameters such as hardness, elasticity, and damping characteristics, the system achieves effective impact protection in a minimal thickness, balancing protection effectiveness with wearer comfort and dynamics.
